Figure 2.17 4-20mA Output Connections
Connecting the Transducer
The XM-320 will accept signals from a linear variable differential transformer
(LVDT), non-contact eddy current probe, or a rotary cam (valve)
potentiometer.
Connecting a Non-contact Sensor
The following figures show the wiring from a non-contact sensor to the
terminal base unit of the XM-320 module.
ATTENTION
The 4-20mA outputs are functionally isolated from other
circuits. It is recommended that the outputs be grounded at
a single point. Connect the 4-20mA (-) to the XM terminal
base (Chassis terminal) or directly to the DIN rail, or
ground the signal at the other equipment in the 4-20mA
loop.
ATTENTION
You may ground the cable shield at either end of the cable.
Do not ground the shield at both ends. Recommended
practice is to ground the cable shield at the XM-320
terminal base and not at the transducer. Any convenient
Chassis terminal may be used (see Terminal Block
Assignments on page 20).
